ON Semiconductor has released the first two devices from
its new VE-Trac family of power modules for high voltage automotive traction
inverters. These two power integrated module (PIM) devices boast high electrical
and thermal performance while providing scalability and automotive reliability
to the rapidly growing market for traction inverters, says ON Semiconductor.
The first two devices to be released are well suited for
use in the main traction inverter of all types of electrically-powered vehicles
including battery electric vehicles (BEV), plug-in hybrid electric vehicles
(PHEV) and full hybrid vehicles (HEV). With the release of these two devices,
ON Semiconductor enables two traction inverter design platforms: VE-Trac Dual
and VE-Trac Direct.
VE-Trac Dual will be a collection of Dual Side Cool (DSC)
half bridge modules that are stackable and scalable within a compact footprint
for traction applications. VE-Trac Dual can be a platform solution for traction
inverter applications ranging from 80kW to 300kW with minimum mechanical
redesign. The first released VE-Trac Dual device is the NVG800A75L4DSC. The
module is rated to 750V at 800A making it double the capacity of currently
available competing devices. Market-leading thermal performance is achieved
through the utilization of highly-effective dual-sided cooling.
The NVG800A75L4DSC is an AQG-324 qualified module with an
embedded smart IGBT that provides a faster reaction time for the integrated
over-current and over-temperature protection features and delivers a more
robust overall solution. The absence of any wire bonds in the module doubles
its rated lifetime. Additional devices within the VE-Trac Dual platform with
higher voltages and various current level options will be released over the
coming months to allow a wide range of emerging applications to be addressed.
The VE-Trac Direct platform, meanwhile, offers
best-in-class performance and benefits, including direct cooling for excellent
thermal performance, says the company. The first release on this platform is
the AQG-324 qualified NVH820S75L4SPB. The device is housed in a six-pack
configuration that is widely recognized and adopted by automotive OEMs and
systems providers; this will allow multi-sourcing to be achieved with minimal
layout changes. Due to become available in multiple power classes, the VE-Trac
Direct platform will allow simple and rapid scaling of power for different
vehicle platforms and applications.
Both VE-Trac Direct and VE-Trac Dual platforms are able
to operate continuously at junction temperatures up to 175°C, allowing more
power to be delivered within the compact footprint of the modular solution.
